Pippa Middleton and her fiancé James Matthews attended the Christmas service at St Marks Church in Englefield, where she is reportedly getting married next year on 20 May.

The prospect wedding venue was graced by the 33-year-old's elder sister, Duchess Kate, Prince William and their children Prince George and Princess Charlotte.

Pippa's parents Michael and Carole Middleton were also in attendance at the Christmas service near their £4.7million mansion in Berkshire.

Christmas celebrations at the Middletons' ahead of Pippa's 2017 nuptials were a break from traditions for royal couple – Kate and Prince William.

The couple, who usually attends the church service at the Queen's Sandringham estate in Norfolk, took part in festivities at Kate's parents' home in Bucklebury.

If rumours are to be believed, the Middleton family seems to be going the extra mile to make Pippa's last bachelorette Christmas special.

Pippa is all set to marry her 41-year-old fiancé next year in May at a modest ceremony in St Marks Church. Following the intimate wedding, the couple is expected at the Middleton house for a homely reception party that will include a luxe marquee set up for the guests in the garden.

While Pippa's wedding details sound like a close family affair, highlight of the ceremony undoubtedly seems to be the appearance of Prince George and Princess Charlotte as page boy and flower girl at their aunt's marriage. Although the young royals would be shouldering important duties, their mother Duchess of Cambridge won't be seen as a bridesmaid at the wedding.

Following the much-anticipated ceremony next year, Pippa and Matthews are looking forward to "having children and leading a quiet life," according to reports.

Other rumoured wedding details include a special white dress by celebrity designer Giles Deacon for Pippa and bridal bouquets from the Lavender Green florist in Chelsea, London.
